*Megan Clark is one of the main characters in The Amazing Spiez!. In the Clark family, she is the older twin sister of Marc Clark and the only female sibling in the family.

Megan is a highly energetic girl. When her brothers doubt her abilities as a girl, Megan seems to be angry and then prove them wrong. In "Operation Terrible Thirteen", the boys are playing baseball, when they cannot catch the ball, Megan jumps up into the air, kicks the ball with her feet, and rolls on the floor with the ball cradled by her feet. She seems to be confident in herself and is often smiling or grinning. Megan is also sarcastic and make cynical comments for some reasons, especially to villains. She is also described as a 'tomboy” by her brothers.

With a 'do or die' attitude and very competitive. Megan likes all of the boys and is very driven and determined when it comes to talking or impressing one. In "Operation 50 Foot Hacker", Megan falls for the new boy Paul and tries to get taller to impress him, later in the episode Megan and her brothers are escaping from Davey Hacker. Megan explains for a more proactive approach with dealing with him. Marc comments that she should get crushes more often because, she is so determined. Tony explains that Megan has an attitude and would not like to be around two Megans. She has some traits of wise, relaxed, usual, and strong attitude when she is on a mission and keeps the boys in line most of the time. Megan also 'jumps' into action with a plan in mind, and for some reasons, she does not tell her brothers about her plans. She seems to be very responsible. She covets her brothers a lot and is annoyed for some reasons but cares a lot about them in her heart. She likes boys that are kissable, strong but gentle, and that cares for her.

She can be a bit boy-crazy. In "Operation Terrible Thirteen", it was implied that she can sing when she explained she had rather do more interesting stuff. Megan is the only one who is not seen with a fear. She and Marc are fraternal twins (not to be identical) She and Marc are really close to each other. Marc and Megan are the only ones in the family that their names start with a "M" Marc and Megan are the only ones that wear the same type of sweater except for different colour, Megan has a zipper in her sweater, and she reveals her midriff. In some episodes, Marc and Megan are seen to have their hands in their pockets of their sweaters a lot. Her hoodie (she most often where's when not on a mission) reveals her midriff. She is good into hacking into computers and technology and stated Marc taught her how. Megan has a personal nickname for friends and family: 'Jockstrap' (Lee), 'Genius' (Marc), 'Brony' (Tony) and Buck teeth (Tami). She is approximately 5'0 in height. Her favourite activity is recycling. She tends to scream at her brothers a lot. For some reasons, she snores in her sleep (Operation: Forgotten Island). She keeps her MP-Com in between her back and her pants. In "Operation Crabby Bob", we can see a shot of part of her bare back.
